STARS BEHIND BARS: INSIDE HELL IN A CELL!!

HOLLYWOOD celebrities get in trouble just like regular folks – some before they were famous and others after they hit it big. The ENQUIRER exposes the bad boys and girls of TinselTown, who all have mug shots to add to their portfolios.

ROBERT DOWNEY JR.

He may be “Iron Man” today, but in the late 1990s, Robert Downey Jr. was staring out through iron bars at the Corcoran State Prison in California. His arrests are the stuff of Hollywood legend, and between the years of 1996 and 2001, it seemed as if the actor was either high, in rehab or behind bars! Though Downey, 48, would sober up and launch a stellar post-drug acting career, including the title role in two “Sherlock Holmes” movies, to this day, his contracts often include a clause withholding a portion of his salary if he relapses during production.

KIEFER SUTHERLAND

Kiefer, 47, son of Hollywood great Donald Sutherland, has had legal troubles that would make his daring “24” character Jack Bauer dive deep undercover! On Sept. 25, 2007, the star was busted for drunk driving and sentenced to 48 days in jail. And he nearly found himself back behind bars in 2009 when he allegedly head-butted designer Jack McCullough in New York, claiming he was defending Brooke Shields, after McCullough bumped into her. Eventually, Kiefer apologized and the cops let him go. His jail experience was anything but fun, the actor has said. “There’s no smoking. The lights never go out, 24/7. You can’t cover anything. You can’t even put your head under a blanket. All the cells have cameras in them.”

WESLEY SNIPES

The taxman cometh – and he nabbed Wesley Snipes! The 51-year-old actor was convicted in 2008 of willful failure to file tax returns. Although they were only misdemeanor charges, the Feds weren’t playing around. Snipes was slammed with a three-year prison sentence, which he served at McKean Federal Correctional Institution in Pennsylvania. Snipes, whose career got off to a dynamite start with “White Men Can’t Jump” with Woody Harrelson, got out of prison in 2013 and is already back in the showbiz game, due to appear in “The Expendables 3” along with a star-studded cast including Sylvester Stallone, Jason Statham, Jet Li, Dolph Lundgren, Harrison Ford and Arnold Schwarzenegger.

MARTHA STEWART

Domestic diva Martha, 72, found her own goose cooked when she was convicted in March 2004 of lying to the Feds about a stock sale and was shipped off to the Alderson Federal Prison Camp in West Virginia. Martha joked that her prison moniker was “M. Diddy” but, she added: “It was terrible – I lost a fortune.” Not surprisingly, she spent her time behind bars doing ceramics and created an entire Nativity set. She said of the experience: “This was a test. I kept my head up. I kept my spirit high, and I moved on.” When she was released on March 4, 2005, her torment was still not over – she was on home confinement in Bedford, N.Y. Fitted with an ankle monitor, she was allowed to leave her home for only 48 hours a week for work. In total, she was subjected to two years of supervised release.

MIKE TYSON

Badboy boxer Mike could not be beat in the ring, but he was knocked out in court after Miss Black Rhode Island Desiree Washington accused him of rape in 1991. Convicted of the crime on Feb. 10, 1992, he lost his appeals and was sentenced to six years in prison and four years’ probation. He served three years at the Plainfield Correctional Facility in Indiana. When he got out, Tyson regained his championship belts easily, but Evander Holyfield took the crown from him by TKO in 1996 – and it was all downhill from there. Tyson was arrested again in 1998 and served three and a half months for assaulting two motorists during an altercation. Tyson, 47, has said: “My whole life has been a waste – I’ve been a failure.” There have been two more arrests since the road rage incident – for cocaine possession, DUI and fighting a photographer – but he got off the hook with wrist-slap charges on those. a house for a marijuana buy that spiraled out of control, leaving one man dead. He served 18 months of hard time on a five-year sentence.

LINDSAY LOHAN

Lindsay’s legal woes rival Robert Downey Jr.’s! The actress – whose charges have run the gamut from DUI to jewelry theft – has appeared in court at least 20 times in front of four Los Angeles judges who have now found her in violation of probation six times and sentenced her to a total of nine months in jail. In reality, Lindsay has spent about two weeks behind bars in six trips to the Los Angeles County Jail, served 35 days under house arrest and worked about 67 days of community service at the county morgue. And she’s only 27!

DANNY TREJO

The 69-year-old “Machete Kills” star got involved with drugs at the tender age of 8 in the Echo Park section of Los Angeles. After spending time in a juvenile facility, he graduated to hard time in six of California’s meanest prisons – San Quentin, Folsom, Soledad, Vacaville, Susanville and Sierra. He started his showbiz career as an extra and appeared in hundreds of films, always as the villain until the “Machete” franchise turned him into a good guy – sort of. “I’m so blessed,” Trejo said. “I’m still scared that somebody’s going to wake me up and say, ‘Hey, we’re still in prison! Let’s go to chow!’”

CHRISTIAN SLATER

Christian found himself in big trouble in 1997 after he punched girlfriend Michelle Jonas in the face and attacked a friend of hers, a janitor and a police officer who tried to intervene. He was sentenced to 100 days in rehab, followed by three months in jail and then an additional three months in a residential treatment facility. It wasn’t Christian’s first run-in with the law – he also had two arrests for drunk driving in 1988 and 1989. In the latter, he kicked a cop while trying to get away and was tossed in the slammer for 10 days. And in 1994, he was arrested after trying to board a commercial airplane in New York with a gun, which got him community service. Christian, 44, admitted: “I consumed a lot of drugs and alcohol. I blanked on the whole thing.” Fortunately, he’s turned his life around. Now clean and sober, the “Soldiers of Fortune” star married Brittany Lopez, 26, in December, and is working steadily, including a role in the upcoming ABC TV drama “Mind Games.”
